My quest for a Billion. Have not done it yet, just put up mid 400 million tonight, current high score is mid 500. On a previous T2 I owned earlier this year, I posted 700 or 800 million, I forget. Stock settings, and abusing the extra ball features is a must. My current is set to wide right outlane.
It's not too hard to get in the few hundred millions, but scoring slows wayyy down when it's more difficult to light your left lane rewards (because the 3 bank targets go out quick) and when it takes multiple shots to hit several targets via the cannon. A way I counter this is to get the right lane lit up to 5 million per shot (love this shot too) early in the game and later as well. Keeping in mind, this is only PER BALL. It goes back to peanuts at balls end. I also find this works great in payback time, because you are getting 5 million for the shot, and 5 million for payback.
Of course, this quest would also gain greatly with a few SUPA JACKPOTS
What ways are others playing/scores?
